A gay fuck club is a great idea. It solves three major problems. First it makes all member feel good about themselves. They don't have to be self conscience about themselves or their performance and second, it gives guys that are past their erection prime a place to continue participation in the lifestyle and third, it allows married guys a safe place to play away from home.
I participated in such a club for many years until the main member moved away from the city. He was single and had a house big enough for 10-15 guys to play around in. We got together once a month on a week day between 11:00 AM and 2:00 PM. There was always someone there to play with and each person brought some refreshments for general use. We had very strict rules about being sloppy, messy and being a general asshole. Rubbers were used on all occasions with no exception. It was interesting to see the 2somes, 3somes or moresomes the members could get into. If you can get one guy with the desire and facility to do it, it could become a great adventure.
